Product Inquiry

The automatic window opener from the quality brand GFP ensures that your plants in the cold frame do not suffer from heat accumulation. This is achieved by a clever mechanism. A special oil expands from approx. 72 degrees Fahrenheit in the opening piston, whereby the window is pushed upwards and opens automatically. The perfect and carefree solution if you are not at home to ventilate yourself or have forgotten to ventilate.

Further special features of the automatic window opener:

  • Automatic measurement of the interior temperature of your cold frame
  • Practical protection of your plants from changing temperatures (the window closes automatically when the temperature drops)
  • No power connection required
  • Lightweight construction
  • The linkage can be unhooked, which allows a wide window opening and smooth working in the cold frame
